Method to compute the "parallel" mean and the SEM. The spectral values are summarised across members of a collection of spectra or of a spectral object containing multiple spectra in long form.

If x is a collection spectral of objects, such as a
"filter_mspct" object, the returned object is of same class as the
members of the collection, such as "filter_spct", containing the
summary spectrum, with variables with names tagged for summaries other
than mean or median.
An R object Currently this package defines methods for collections of spectral objects.

Method specializations compute the mean and SEM at
each wavelength across a group of spectra stored in an object of one of the
classes defined in package 'photobiology'. Omission of NAs is done
separately at each wavelength. Interpolation is not applied, so all spectra
in x must share the same set of wavelengths. An error is triggered
if this condition is nor fulfilled. The value passed as argument to `mult`
